Hi all, this isnt a pressing issue but merely something that gets under my skin. I have recently had a fall out with my neighbour due to a third party wall and as a solution I erected a fence on my land to act as a shield between my garden and his wall. There is full access to his wall and a good 12" space between wall and fence. I have never stopped him from accessing the wall to his property. Anyway, to the point. My neighbour keeps banging on about me being in breach of covenant by altering an aspect to my property as its leasehold.

My lease is for 999 years - I have 975 years left on the lease. It is £10 per year fixed. My house is a semi and is worth £240,000.

At any point will the fact my property is leasehold affect the value of my property and is it really worth buying the lease? Does anyone know how much it will be?

A chartered surveyor owns the lease. I never get bothered by them - only a letter each january asking for the ground rent. I have extended the property to the rear as have my other neighbours without notifying the leaseholder ( they never either ). Will the leasehold status affect the value of my property long term??
